> The Allwinner H616 has two switchable peripheral SRAM regions:
> 
> - The VE SRAM is a 2 MB dedicated SRAM for the Video Engine. CPU access
>   to this region is enabled by default. CPU access can be disabled,
>   after which reads will show the same stale value for all addresses,
>   while writes are ignored.
> 
>   The mux value for this region is different from previous generations.
> 
> - The SRAM C region is an alias of the first 128 KB of VE SRAM, plus 64
>   KB of DE SRAM. The latter is otherwise unaccessible from the CPU. When
>   CPU access is disabled, the whole region reads as zero, while writes
>   are ignored.
> 
>   The mux value for this region is the same as on the A64 and H6.
> 
> Add compatible strings for both of them.
